AD NUMBER: 2009-22-11

SUMMARY: This AD
results from a mandatory continuing airworthiness information
(MCAI) AD issued by the aviation authority of Canada. The MCAI AD
states that, during a preflight check, it was observed that the
swashplate link assembly bearing had moved in the lever race,
making contact with the swashplate support. The MCAI also states
that further investigation revealed that the bearing had not been
staked correctly during manufacture. That condition, if not
detected, could result in failure of a bearing, failure of the
swashplate link assembly, and subsequent loss of control of the
helicopter.
